RTX 4070 Ti GAMING X TRIO 12G All displayports failed after lightning struck
Hey, I have this GPU (MSI GeForce RTX 4070 Ti GAMING X TRIO 12G). After a lightning struck all dispaylports don´t work anymore but the one hdmi does in fact function properly. Has anyone a suggestion, what the error may be? Is it the GPU core itself that is damaged or is it a simple replaceable chip that is fried?

Just starting out in electronics repair and teaching myself as I go.
I have here a Corsair RM650 ATX PSU, which I'm treating as a learning project that if successful may be used in my PC.
Fuse was blown, probable power surge from lightning, followed the circuit and found, a dead relay and all the diodes and resistors around the bridge rectifier shorted. Rectifier and MOSFETs seem fine on the LCR.
Also found these tiny diodes on the other side, a few shorted, the rest seem fine. But they're not all marked as Zener on the pcb. So I'm unsure what these should be replaced with.... -
Old friend was throwing this away after lightning struck their house. Standby power light is on but no backlights will come on. However when I disconnect the main board from the power boards, the backlights immediately come on. This leaves me to believe problem is with the main board. Any help would be greatly appreciated. -

Lenovo Legion 5 15ARH05H, NM-D281 Rev 1.0, "BIInitializeLibrary failed 0xc0000185" and bios freezingDear members,
I have a problem with this machine that still I can't solve, I hope some of you can suggest me something.
I was the first one to open the machine and touch the mainboard, in fact the Lenovo seal was intact the first time that I unscrewed all the internal screws.
The ower told me that it was working very good until Windows kicked "something like a firmware update" (owner's words) then the system started acting weird.
When you try to start it, some seconds after having pressed the power button, Lenovo splashscreen appears, then after 1 second, in the...
